ADF4002 Description
The ADF4002 frequency synthesizer is used to implement local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and programmable N divider. The 14-bit reference counter (R counter) allows selectable REFIN frequencies at the PFD input.
